SEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 416,542,"dated December 3, 1889.

Application iled March ll, 1889.

To all whom it may concern:

Be it known that I, WILLIAM D. ARNETT, of Springfield, in the county of Clark and State of Ohio, have invented certain Improvements in Seeding-Machines, of which the fol-` against the under side, and illustrating more' particularly the shaft and supports by which the drag-bars are carried. Fig. 2 is a side elevation of one of the drag-bars with the draft-connections to the main frame,Y one of the disks being removed to expose other parts to View. Fig. 3 is a longitudinal vertical central section through the drag-bar and its attachments. Fig. 4 is a vertical section on the line 2 2 of Fig. 2, looking rearward. Fig. 5 is a side view of one of the weighted rods for depressing the drag-bars. Fig. 6 is a horizontal section on the line 3 3 of Figs. 2 and 3. Fig. 7 is a perspective view of the plate at the forward end of the drag-bar. Fig. 8 is a side elevation on a reduced scale of my improved seeding-machine.

Referring to the drawings, A represents a rigid rectangular main frame, constructed of wood or other material in any suitable manner', and mounted, as usual, upon two groundwheels B. p

C represents a series of longitudinal dragbars arranged side by side, as usual, the forward end of the series being mounted on a horizontal cross-shaft D, lying beneath the main frame. This shaft D is supported by vertical arms d d', &c., extending rigidly downward from a cross-bar (Z2 of the main frame. It is also braced .and stiftened by means of bars (Z3, extending upward to the forward part of the frame in a manner very similar to that in a patent heretofore granted to me.

To the shaft D, I connect by a strap e or seria No. 302,863. (No model.)

equivalent connections, a transverse draftbar or evener E, to which I connect at the middle by a clevis e or other suitable coupling, a doubletree F, which is Yin turn pro- ,vided with singletrees for two, three, or more draft-animals side by side. Under this arran gement; the power required to advance the machine is applied through the shaft D directly to the forward ends of the drag-bars, instead of being applied indirectly through the frame, as usual. This is advantageous, vin that it admits of the parts being of lighter construction than would otherwise be admissible, and also in that it overcomes the tendency of the frame to tip downward at the front and throw an excessive weight on the necks of the draft-animals. The frame will be provided, as usual in machines of this class, with a central tongue or draft-pole bolted rigidly thereto and extending forward, as shown at G.

An important feature of the present invention resides in the construction of the dragbar and its attachments. Each bar consists, primarily, of an upper longitudinal strap or bar c and a lower strap or bar o', the two being applied at their forward ends to the upper and lower faces of the draft-head c2 and bolted or riveted firmly thereto. The upper member c is straight, or substantially so,

iss

while the lower member is carried downward at the rear end and united to the upper member by a bolt or rivet.

The draft-head c2 is made, as shown in Fig. 7, in the form of an open plate or ring anged at the top and bottom to receive the parts c o', and provided at its ends with tubular trunnions or sleeves to receive the supportingshaftD. These draft-plates afford widely-separated bearings for each drag-bar, so that its IOO plied a \v'erticallyadjustable block or casting o, having at its two sides the journals or trunnions c", to carry the respective furrowopening disks. The plate c5 is held to its place by a horizontal bolt ci, passing through the plate and a vertical seat in the standard to the back o 'f the latter. This construction admits of the block ci and the disks being raised and lowered in relation to the under face or shoe of the runner in order to determine the depth of the furrow, the descent of the disks being limited by the shoe or runner, which rides upon the surface.

Over the top of the standard upon the upper surface of the part c is seated a plate c", having an upright ear to carry the transverse pivot-bolt el, which supports the arms or ears of the two seed tubes or conductors II. These tubes, which are of oval or elliptical form in `cross-section, are mounted one on each side of the drag-bar, their lower ends passing downward close to the inner faces of the respective disks imposition to deliver seed into the furrow. It will be observed that the supporting arms or ears of the seed-tubes extend forward therefrom, and that they rest on top of the plate c. This arrangement permits the lower end of each tube to tip backward and' upward in the event of its encountering an obstruction, and gravitating to its original posit-ion as soon as it is set free.

In order to maintain the proper separation of the lower ends of the seed-tubes, I apply a wooden block I at the under side of the part c, and in position to bear against the inner sides of the conductors. This block may be secured in position by a vertical bolt 27, which also serves to unite the standard and the part c. I commonlyprovide the standard with a central depending rib or lug c, which enters a slot in the top of the separatingblook I, tol keep the latter in its central position.

For the purpose of forcibly depressing the drag-bar and disks when operating on sod or unplowed land, I connect to the rear end of each tube, as in previous machines, a vertical rod J, which is provided with suitable weights. I now connect this rod to the dragbar in the peculiar manner shown in Fig. 2. The upper member c of the drag-bar has its rear extremity curved upward and then downward, provided with' the perforation c* 2, through which a link or ring el" is inserted. The lower end of the rod J is fashioned into a hook, such as shown in Fig. 5. When the rod is in a horizontal position, this hook may be inserted through the link, as shown; but on turning the rod to its upright or operative position its detachment becomes impossible.

Having thus described my invention, what I claim isl. In combination with the sustaining-shaft and the series of drag-bars, the series of draftheads, each having the sleeves mounted on the shaft, and the flanged faces bolted to the drag-bars.

2. The draft-head for a seeder drag-bar, consisting of the open plate provided with the sleeves and with the Hanged surfaces to receive the drag-bar.

3. In combination with the upper and lower members of the drag-bar, the intermediate standard, the block provided with the disksustaining axles and applied to the standard, and the clamping-bolt uniting the block and standard, substantially as shown'.

4. In combination with the drag-barand the f urrow-ppenin g disks carried thereby, the hinged gravitating conductor-tubes and the intermediate spreading-block attached to the drag-bar.

5. In a seeder or kindred machine, the combination of the wheeled main frame, the crossshaft rigidly supported thereunder, the dragbars jointed directly to said shaft, and the draft-bars also connected directly to the shaft, whereby the draft is transmitted directly to the drag-bars instead of being transmitted through the frame, as usual.

In testimony whereof I hereunto set my hand, this 16th day of February, 1888, in the presence of two attesting witnesses.
